Operation Manual

PCI switch card assembly
The PCI switch card assembly, mounted on the top rear of the server frame
adjacent to the adapter slots, contains one switch for each of the six adapters. This
ensures that power is disconnected from the associated adapter if you attempt to
open the adapter latch and remove an adapter.
Note:
v Read “Installation guidelines” on page 29.
v Read “Safety information” on page 147.
v Read “Handling static-sensitive devices” on page 30.
Complete the following steps to remove and replace the PCI switch card assembly:
1. Turn off the server and all peripheral devices; then, disconnect all power cords
and external cables.
2. Remove the top cover (see “Removing the cover and bezel” on page 32).
3. Remove all full-length adapters and adapter insulators (see “Removing a PCI or
PCI-X adapter” on page 36), making sure to place the adapters on a
static-protective surface.
4. Disconnect the PCI switch card assembly cable from the server.
5. Grasp the two adapter switch card release latches and slide the assembly away
from the server chassis; then, lift it out of the server.

being serviced.
Release latches
6. To replace the PCI switch card assembly, lower the assembly into place so that
the lips on the bottom of the EMI shielding material fit into the chassis at the
rear of the server, and slide the card into place until the two release latches
snap securely.
7. Connect the cable from the PCI switch card assembly to the I/O board and
install the adapters and adapter insulators that were removed in step 3.
